- FOR SHIMANO DEORE M555/ NEXAVE C900
The Shimano 105 groupset continues to evolve. This Shimano 105 5800 11-Speed Groupset has successfully narrowed the gap between 105 and Ultegra. Whilst both groupsets undeniably benefit from the joys of trickle down technology of the elder statesman, Dura-Ace, the performance of Shimano’s 105 11-speed groupset is precise, efficient, and reliable.
The Ultegra 6800 series is “pro-proven” as it is a direct trickle down from the Shimano Dura Ace groupset. It stands for state-of-the-art technology, proven in pro races, the technology used in the new Ultegra 6800 series with 11 speed, newly designed brakes, new chain treatment etc.
